When I try to set a PARAMETER using the Xml Configuration I get the following error:

None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'LM.AM.Core.Services.EmailService' can be invoked with the available services and parameters:
Cannot resolve parameter 'System.String testSmtp' of constructor 'Void .ctor(System.String)'.

I've checked the container is aware of the xml parameter and I've followed the Wiki as close as I can, but for some reason the parameter is not resolving on the only constructor and I'm receiving the above error.

This should be pretty simple to get going. Can anyone provide some suggestions on what I
can try to get this working?
